Green hydrogen, which may be made through water electrolysis, offers a potential solution for the sustainable use of electricity that is generated from renewable main supplies. Therefore, hydrogen is an important energy transporter that is easily transportable and stored, and it is also an essential feedstock for making chemical substances like fertilizers and industrial chemicals. To address the present difficulties in guaranteeing a renewable energy supply that is beneficial to the environment, the current research investigates the feasibility of transferring renewable hydrogen by pipeline from areas with significant renewable energy capacity to huge consumer centers. Therefore, this study evaluates the ecological effects of international hydrogen supply chains (HSC) in relation to the achieved working hours of locally producing hydrogen and the necessary pipeline route for hydrogen transportation. By integrating life cycle assessment with economic evaluation under green finance frameworks, the analysis identifies key environmental hotspots and quantifies the impact of pipeline route length, compressor energy sources, and local hydrogen production efficiencies. Additionally, a trade-off arises in terms of the environment when considering the optimal local circumstances to generate renewable hydrogen compared to the distance that hydrogen must be transported to consumers. However, as the proportion of renewable resources in the power mix used to run the pipeline network's compressor units increase, the importance of transit distance declines. The results suggest that with targeted green financing and policy incentives to decarbonize energy inputs, long-distance hydrogen transport via pipelines can be both economically viable and environmentally sustainable, supporting the development of robust global green hydrogen supply chains.
